[Quantitative evaluation of motor activity of children with hyperkinetic syndrome].

Quantitative assessment of children's motor activity is necessary to objective classification of children according to their motor activity. The authors of the study made a quantitative assessment of motor activity of 55 boys in the age from 8-12, with normal IQ, using motor-scopic-motor-metric method. Global motor activity was assessed together with the activity of the head, trunk, and limbs, in such testing situations as sitting, standing, lying, and reading. It was found out that quiet children make 6.4 movements per minute, and hyperkinetic children make 21.4 movements per minute. Assessment of motor activity of upper limbs (arms, hands, fingers) is a sufficient factor to assess motor activity of children and verify their hyperkinetic syndrome. In such conditions 3.1 movements per minute is a borderline for quiet children and 6.4 movements per minute for hyperkinetic children. It was found out that the growing-up process leads to lessening of motor activity, especially in hyperexcitable children.
